One good property of the woods which cover this island is, that they are every where of easy access, as there is no undergrowth, except in some of the deepest valleys, where the fern grows exceedingly high, and of which there are very large trees, with trunks of considerable solidity.[270] Some of the English who had been formerly here, had sowed turnips, which have spread much, as have also two or three plantations of small pompions; but my men never had patience to let any of these come to maturity. We found also plenty of water-cresses and wild sorrel. Some of the hills are remarkable for a fine red earth, which I take to be the same with that of which the inhabitants of Chili make their earthenware, which is almost as beautiful as the red porcelain of China. The northern part of the island is well watered by a great many streams which flow down the narrow valleys; and we found the water to keep well at sea, and to be as good as any in the world. Down the western peak, contiguous to the Table Mountain, there fall two cascades from a perpendicular height of not less than 500 feet. These are close together, and about 12 feet broad. What with the rapid descent of these streams, and the numerous palm-trees growing close beside them, adorned with vast clusters of red berries, the prospect is really beautiful. We should have had no want of goats, could we have conveniently followed them in the mountains. The Spaniards, before they settled in Chili, left a breed of goats here, and have since endeavoured to destroy them, by leaving a breed of dogs, but without effect. Cats are also very numerous, exactly resembling our household cats in size and colour; and those of our men who eat of them, assured me they found more substantial relief from one meal of their flesh, than from four or five of seal or fish; and, to their great satisfaction, we had a small bitch, which, could catch almost any number they wanted in an hour. There are not many sorts of birds; but the sea on the coast abounds with a greater variety of fish than almost any place I was ever in.
